Abstract

The invention is based on an electric device, in particular an electric hand tool, having a removable power supply unit (18, 70, 104), an accommodation region (16, 102, 132, 144, 156) for accommodating the power supply unit (18, 70, 104), and a locking device (20, 76, 114, 134, 146, 154) for locking the power supply unit (18, 70, 104) to the accommodation region (16, 102, 132, 144, 156). It is proposed that the locking device (20, 76, 114, 134, 146, 154) is provided for the purpose of unlocking the power supply unit (18, 70, 104) from a locked state—by means of a force which is exerted on the power supply unit (18, 70, 104) and moves the entire power supply unit (18, 70, 104) in relation to the accommodation region (16, 102, 132, 144, 156).
